Question 709282: Please I need help the homework says to use base ten blocks to divide these decimals, using the rectangle model of multiplication and division. Before you start, think: which numberis an area, and which is a lenght? How can you make 0.1 of a square meter. To let you know our professor does not want to solve the problems as a decimal, so we have to change the problem into a fraction and then solve. I need help with two problems
A.) 0.24 / 1.2
B.) 0.24 / 2

A.) 0.24 / 1.2
As fractions
24%2F100 / 12%2F10
invert the dividing fraction and multiply
24%2F100*10%2F12
we cancel 12 into 24 and 10 into 100, leaving
2%2F10 reduces to 1%2F5
:
B.) 0.24 / 2
As fractions
24%2F100 / 2%2F1
invert the dividing fraction and multiply
24%2F100*1%2F2
24%2F200 reduces to 3%2F25
