Look at mina's work below 10 7/12 - 9/12 = (10/12 + 7/12) - 9/12 = 17/12 - 9/12 = 8/12 is mina's solution reasonable. Explain
RSB [31]
10 7/12 - 9/12=(10/12+7/12)-9/12=17/12-9/12=8/12

127/12-9/12

Nope. Her solution doesn't seem reasonable. In order to subtract 9/12 from 10 7/12 you must convert 10 7/12 to an improper fraction. You should then have 127/12 where she has 10/12.

Hope this helps! =)

rodikova [14]

Answer:

Interest will amount to $142.58

Total amount Levi will have to pay back at the end of 6 months=$7271.58

Simple interest=principal×rate×time

=$7129×0.04×0.5

=$142.58

Interest will amount to $142.58

Total amount Levi will have to pay back at the end of 6 months

=principal + total interest

=$7129+$142.58

=$7271.58
