Write three ratios equal to 7/35? a 1/7, 2/14, 3/21 b 5/7, 10/7, 15/7 c 7/35, 7/40, 7/45 d 1/5, 2/10, 3/15 i think it is c or d.

Step-by-step explanation:

To find the three ratios we only have to find the most simple ratio of , and then find the other ratios that are equal to it.

So,

Also, , by multiplying by two each part of the fraction.

Similarly, , by multiplying by three.

Therefore, comparing all these ratios, all are the same, they are equal to . So, the option that correctly has these choices is D.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

ratio is 2 : 9

the answer is three

13.5 : 3
