What is 8 3/4% expressed as a fraction?<br><br><br> 8/100<br><br> 7/80<br><br> 7/40<br><br> 8/25
Lelu [443]
ANSWER:

7 / 80

8 3/4% expressed as a fraction is 7 / 80.

STEP-BY-STEP EXPLANATION:

Write 8 3/4% as a percentage with a decimal:

= 8.75%

Convert 8.75% to a fraction:

= 8.75% ÷ 100

= 8.75 / 100

Make the numerator a whole number by multiplying both the numerator and denominator by a 100:

= ( 8.75 × 100 ) / ( 100 × 100 )

= 875 / 10000

Divide the numerator and denominator in the fraction by their highest common factor ( HCF ):

HCF = 125

THEREFORE:

= ( 875 ÷ 125 ) / ( 10000 ÷ 125 )

= 7 / 80
