Question

What should the following equation be multiplied by to eliminate the decimals?6.74x-1.026=0.138.

a.1
b.1000
c.100
d.10

Answer 1

b.1000

Explanation:

6.74x-1.026=0.138

The smallest decimal goes to the thousandths place, so we need to multiply by 1000

.138

. tenths hundredths thousandths

Another way to look at it

.138 = 138/1000 so multiply by 1000 to get rid of the decimal

1.026 is to the same place value so we could pick either one to determine what to multiply by
