Let's consider the number of pennies that we need to be [tex]p[/tex]. Given this we can say that we are trying to find [tex]p[/tex] in the expression:

[tex]\dfrac{3}{4} p = 42[/tex]


Let's multiply both sides by [tex]\frac{4}{3}[/tex] to get:

[tex]p = 56[/tex]


We would need 56 pennies.

3/4 6/4 9/4 12/4

12/4=3 inches for 4 pennies so

42 inches equal 56 pennies

you can also do 0.75 times 42
