Question

Jenny and Lenny pick 1/4 and 1/3 of a tree full of apples, respectively. Penny picks the rest of the apples.If Lenny picks 7 more apples than Jenny does, how many apples does penny pick

Answer 1

Answer:

Penny picks 35 apples

Step-by-step explanation:

first, you need to multiply the fractions to get equal denominators.

(1/4)*3=3/12 and (1/3)*4=4/12

then add the results,

3/12+4/12=7/12

to work out what fraction was picked by Penny, use 12/12(total amount as a fraction with equal denominator)

12/12-7/12=5/12

then to work out how many apples were picked by Penny(P), Jenny(J), and Lenny(L)

J=3/12, L=4/12, P=5/12.

if Lenny picks 7 more than Jenny, then each twelfth of the apples is 7 apples. therefore,

12*7=84 total apples

Penny picks 5 twelfths, therefore,

5*7=35 apples
