Which pair of ratios can form a true proportion?

A) 1/2, 6/10
B) 6/8, 5/20
C) 3/5, 6/10
D) 3/9, 7/80

wdym ''asking for questions will get you banned'' literally everyone answers questions

P.S. If you took this test before, can you PLEASE give me some answers to the whole test???

I'm sorry. Can you tell me how to answer the question that I wrote? Not the answer? Sorry.

I just really suck at math.

Simplify the fractions and find out which pairs are equal.

What’s the correct answer

To determine whether a pair of ratios can form a true proportion, we need to check if the cross-products are equal.

The cross-products are found by multiplying the numerator of the first ratio with the denominator of the second ratio, and then multiplying the numerator of the second ratio with the denominator of the first ratio.

Let's check each option one by one:

A) 1/2, 6/10
Cross-products: (1 * 10) = 10 and (2 * 6) = 12
Since the cross-products are not equal (10 is not equal to 12), option A is not a true proportion.

B) 6/8, 5/20
Cross-products: (6 * 20) = 120 and (8 * 5) = 40
Since the cross-products are not equal (120 is not equal to 40), option B is not a true proportion.

C) 3/5, 6/10
Cross-products: (3 * 10) = 30 and (5 * 6) = 30
Since the cross-products are equal (30 is equal to 30), option C is a true proportion.

D) 3/9, 7/80
Cross-products: (3 * 80) = 240 and (9 * 7) = 63
Since the cross-products are not equal (240 is not equal to 63), option D is not a true proportion.

Therefore, the pair of ratios that can form a true proportion is option C) 3/5, 6/10.

should not even say that

The Weekend is right. Asking for answers is cheating and can get you banned from posting here.
