Choose the ratio below that is equivalent to the greatest fraction
Mumz [18]
Ratio 5:2 as fraction should be 5/2

as you know 5/2 = 2.5

This is the biggest compared to 9/5, 8/5 and 2/7

9/5 < 2
8/5 <2
2/7 < 1

so 5/2 is greatest

35/40 reducing fractions
laila [671]

Answer: 7/8

What you have to do here is to find the highest number which can be divided by both. Or you have to divide both the numerator and denominator until it can not be divided by any number anymore. You can do this by finding the highest common factor (<u>HCF)</u> of both the number, 35 and 40.

Highest Common Factor: HCF of two or more numbers is the greatest factor that divides the numbers. For example, 2 is the HCF of 4 and 6.

So, the highest number which divides 35 and 40, is 5. Now 35 divided by 5 is 7 and 40 divided by 5 is 8. The final answer is 7/8 and there is no more numbers which can divide both of them by a specific number.
