Question

4 27/125 as a decimal

Answer 1

Answer:

Step-by-step explanation:

We have been given a mixed fraction - 4 .

there are 4 wholes of 125 and remaining 27. then numerator is equal to 125 x 4 + 27 = 527.

then the improper fraction is .

To write as a decimal , the denominator should be a power of 10. denominator 125 can be multiplied by 8 to get a power of 10.

125 x 8 = 1000. both numerator and denominator should be multiplied by 8

now to write as a decimal, 4216 has been divided by 1000.

when dividing by a power of 10, the decimal point should move to the left.

when dividing by 1000, the decimal point should move 3 decimal places to the left. the decimal point of 4216 is after 6, when it moves 3 places to the left its between 4 and 2. Therefore answer is 4.216, PLEASE, can you give me the brainlies

Answer 2

We have 125 = 5³ and 1/5 = 0.2. Then

1/125 = (1/5)³ = 0.2³ = 0.008

so that

4  27/125 = 4 + 27 • 0.008

… = 4 + 0.216

… = 4.216
