Question

Calculate the solution to each equation below using the indicated method. Remember to check your answers. 1. La Use tape diagrams to find the solution of 10

Answer 1

Given the expression:

$\frac{r}{10}=4$

we have the following tape diagram:

notice that we have 'r' divided in 10 squares, so, if we want this division to be equal to 4, then, each square must have a value of 4, that means, that r = 40
