How would you express 37/40 as a decimal?
dexar [7]
You can put it in a calculator, or do long division on a piece of paper. I would show you how to break it down step-by-step, but doing long division on here is complicated.

All you have to do is find the decimal of a fraction is to divide the numerator and the denominator.

In this case, divide 37 by 40 to get your decimal.

37 ÷ 40 = 0.925

So, the decimal form of 37/40 is 0.925.

Linda bought $87.95 worth of merchandise at an electronics store. She
forsale [732]

Answer:  She paid $66.33

Step-by-step explanation:

The overall amount that you paid for the video game was 87.95. She got 27.79 back as a refund. So you subtract what she paid from her refund. 87.95-27.79 = 60.16.  She also had to pay a fine for the video game. So you add the fine to the amount. 60.16+6.17 = 66.33.

Overall, she paid 66.33.
