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
