What is an equivalent fraction for the following fraction?<br> 5/8....<br> 09/16<br> 8/16<br> 10/16
atroni [7]

Answer:

10/16

Step-by-step explanation:

I looked at the 5 and looked at every other number and you can't multiply evenly with those other numbers. You can only do 5x2 which will get you ten. But that won't work for the other numbers.

Hope this helps :)

If you had 4 quarters and 8 nickels how much money would you have?
spin [16.1K]

Answer and Step-by-step explanation:

A Quarter is equal to 25 cents.

A Nickel is equal to 5 cents.

We have 4 quarters and 8 nickels, so times this amount of coins to their values.

4 × 25 = 100

8 × 5 = 40

Now, we add these together.

140.

This is 140 cents.

After the 100 mark, it turns into a dollar (because there is 100 pennies (cents) in 1 dollar).

So that means the total amount of money we have is One dollar and Forty cents ($1.40)
