Question

Marisa has studies 1 1/2 hours today.That is 3/10 of the time ahe plans on studying today.How long does Marisa plans on studying today? Need help!!!!!

Answer 1

Marrisa plans on studying for 5 hours today!

Explanation:

1.5 hours = (3/10) of X ...... where X is the "number of hours she plans on studying today" and OF means to multiply....

so..... 1.5 = (3/10)X

then you will solve for X!

Multiply by 10 on both sides and you get: 15= 3X

then divide by 3 on both sides and you get your answer! 5 = X
