NO GAINS ON SACRIFICE
NO GAINS ON SACRIFICE Is a Mnemonic to remember a Formula for Gain Ratio and Sacrifice RatioGain Ratio = New Ratio - Old RatioSacrifice Ratio = Old Ratio - New RatioThis Slogan or Proverb is applicable for all Parents who sacrifice for their Children without expecting any Gains for their sacrifices.
This Formula is usefull in application of Profit Sharing Ratio in case of a partnership firm.In case a new partner is admitted into the Business then the old profit sharing is no longer valid and a new profit sharing ratio is required. Besides Bringing capital into the business the new partner is also supposed to bring some additional funds as gift for the old partners. This gift is called as Goodwill. So when the New Partner brings Goodwill Amount into the business this amount is supposed to be distributed to the old partners in Sacrifice Ratio.The Formula for Sacrifice Ratio BeingOld Ratio - New Ratio Similarly when any partners retires from Partnership Firm the Outgoing partner is supposed to get his share in the Goodwill of the partnership firm. In this case the Remaining partner [those who continue to be in Business and do not retire] are supposed to Contribute for Goodwill for the retiring partner. This Contribution is in Gain Ratio whihc is calculated as followsNew Ratio - Old Ratio

Everybody's Daddy, Mother, Sister, Brother, Reunion, Celebration
Estimate, Divide, Multiply, Subtract, Bring Down, Redo (all steps), Check (by multiplying the quotient - plus any remanider times the divisor.) Students use compatable numbers to estimate the quotient. Then - follow each step to complete the division. ALWAYS check by multiplication to find the dividend. Note: If it is a decimal number that repeats - it will never be the exact dividend but will round to the exact dividend.Brenda Woods shared this one & my stuedents added the ist & last words.

Students tend to divide the LARGER # by the SMALLER number and commonly miss these types of items. Also, I teach my students to automatically "annex 0's by writing the "understood decimal, placing it on the quotient bar directly above, and then annexing at least two zeros.

To convert from a Larger metric unit to a Smaller metric unit, think of alphabetical order. You would move from the letter L to the right to get to the letter S.You would move to the left from the S in "smaller" to get to the letter L in "larger."
To convert from a LARGER to a SMALLER metric unit - move the decimal to the Right as many places as indicated by the # of zeros in the ten's power.To convert from a SMALLER to a LARGER metric unit - move the decimal to the Left as many places as indicated by the # of zeros in the ten's power.

MEAN means the Average.MODE is the Most frequent.MEDIAN is the middle in a numerically ordered set of data.Range is all #'s that are located on the number line between the highest & lowest data.
Mean - Add all data & use this sum as your dividend when you divide by the total number of data in the set.Mode- There is NO MODE UNLESS one and only one number appears more than any other number in the data set!Median - There will be two ordinal numbers in the middle of an even set of data. Find the mean / average. This quotient may be a decimal number but there can be ONLY ONE MEDIAN NUMBER!Range - Simply subtract the lowest data # from the highest data #. Note: You usually do not include the extremes unless you are asked to give the range of prices. Ex. Dresses are - $48, $50. $77. $98. In this case, the range of prices is from $48.00 to $98.00 and does include the two extremes.
