Mary has 48 stickers. The ratio is 4:7

divide 48 with 4

48/4 = 12

Multiply 12 with 7

12 x 7 = 84

Mary buys another 8 stickers: 48 + 8 = 56

56:84 is the new ratio

hope this helps

Tara walks 2 miles in 30 minutes At this rate,how far can Tara walk in 45 minutes?​
nevsk [136]

Answer:

Step-by-step explanation:

In 30 minutes she can walk 2 miles. We'll put that as a ratio. 30:2. Now to figure out how much she walks in 45 minutes, we set variable to x and make it stand for how much she walks. We have 30:2 = 45:x We cross multiply to get 30x=90, x=3. Tara can walk 3 miles in 45 minutes.
