Write each decimal as a fraction or mixed number in simplest.

-0.15 = - 7.75 = - 12.54=

= - 3/20 = - 7 3/4 = - 12 27/50

Step-by-step explanation:

For - 3/20, we know that. 1 is a tenth, so half of that, 0.05, must be a twentieth. - 0.15 = - 3 x 0.5, so it's - 3/20.

For the second problem, we'll set the - 7 aside for the mixed number. 0.25 is a quarter, and there's three of them (0.25 x 3 = 0.75), so it's 7 3/4

For the third problem, we again set the - 12 aside for the mixed number. 0.54 is 54 one-hundreths, which is 54/100. we can reduce that by dividing both the numerator and denominator of the fraction by 2, and we get 27/50. Because 27 is prime, it cannot be reduced any further, the answer is - 12 27/50.

-0.15 = - 15/100 = - 3/20

-7.75 = - 7 3/4

-12.54 = - 12 54/100 = - 12 27/50
