The model below is shaded to represent a fraction
which model shows an equivalent fraction

a)

Step-by-step explanation:

a) 4\12 b) 1\4 c) 3\4 d) 3\3

If you’re trying to find 1\3, then you can instantly rule out 3\3.

Let’s find a common denominator (bottom number). This part is quite easy. It would be 12.

To make the 3 into a 12, you have to times it by 4, therefore you have to times the numerator (top number) by 4 as well, making 4\12. This is answer a).

To check the answer, let’s find b) and c) as the denominator 12.

They are both 4, so you would times by 3, making b) 3\12 and c) 9\12. They aren’t 4\12, so we got the answer right.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
