Which fraction represents the decimal 0.12 a) 1/12 b) 3/25 c) 4/33 d ) 33/4

almond37 [142]

Answer:

The fraction that represents the decimal 0.12 is 3/25

Step-by-step explanation:

step 1: find the place value of the last digit in 0.12

Since they are 2 digits in 0.12 the place value of last digit is the 100 th, therefore 0.12 is the same as 12/100

step 2: simplify 12/100 by dividing both the denominator and numerator by 4

that is 12 divide by 4 = 3 and 100 divide by 4 =25

therefore the fraction = 3/25
