Jason: 5/7
Sara: 4/5

Think of it this way: if the total track is a mile, and Jason runs 5/7 of it,  he has run 5/7 of a mile. Then Sara runs 4/5 OF 5/7, with "of" meaning "times," so she runs 4/5 x 5/7, which gives you 20/35, which simplifies to 4/7. You can also think of Sara's distance as 80 percent of Jason's. If she runs "80 percent of the sevenths that Jason ran," that means she ran 4 out of his 5 sevenths.

one pound of grapes costs $1.55. which equation correctly shows a pair of equivalent ratios that can be used to find the cost of
Marat540 [252]

startfraction 1.55 over 1 endfraction is x = 1.55

<h3>What is ratio?</h3>

A ratio in mathematics shows how many times one number is included in another. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six (that is, 8:6, which is identical to the ratio 4:3). (i.e., 8:6, which is identical to 4:3). The ratio of oranges to the overall amount of fruit is 8:14, while the ratio of lemons to oranges is 6:8 (or 3:4). (or 4:7). (or 4:7). A ratio can have any number of values, such as counts of people or things or measures of length, weight, time, etc. In most cases, both numbers must be positive.

EXPLANATION:

Sadly, we are unable to view the list of equations from which you can choose. But if we assume that x Equals the cost of 3.5 kg of grapes, we can construct the following equation

1/1.55 = 3.5/x

x = 1.55
