It means K C F or Keep Change Flip with fractions when multiplying E H I E A L P N P G E
No, you do not.
No but for fractions
You have to make the fractions improper then you switch the devision sign to the multiplying sign and then you switch the numbers around on the second fraction then you just multiply the fractions. When ever you do this think keep switch flip you keep the first fraction alone you switch the sign then you flip the last fraction. Good luck 😍
keep change flip - which means keep the first # - chage the division sign to multiplication- The reciprocal means flip the 2 # ex.7/2-2/7.
u use keep change flip when using integers
You simply put the whole number over one making it a fraction then you flip the reciprocal and divide the two fractions insted of multiplying.
In dividing fractions you have to change division to multiplication and change the second fraction into a recipracol(flip the fraction.
Multiplying fractions is no problem top times top bottom times bottom. Dividing fractions is easy as pie, flip the second fraction and multiply. Your welcome!!!!! (: that is one math jingle.
K = keep the first fraction C = change division sign to a multiplication sign F = flip last fraction You can only use KCF for dividing fractions. i learnt that during math class so
you flip the last (second) fraction, and then you change the divide sign into a times sign. You can then times the fractions from there. You do not need the same denominator to times fractions.
