Correct question

Noah drank 4/5 liter of water Monday before going jogging. He drank 2/3 liter of water after his jog. How much water did Noah drink altogether? Write your answer as a mixed number.

Answer:

1\frac{7}{15}

Step-by-step explanation:

Noah drank 4/5 liter of water Monday before going jogging. He drank 2/3 liter of water after his jog.

To find the total liters of water he drank, we should add up the liter of water  he drank on Monday before going jogging and  liter of water after his jog.

4/5 + 2/3

Find the Lowest Common Multiple for 5 and 3 , which is 15.

= [(4×3) + (2×5)] /15

= 12 + 10/ 15

= 22/15

As a mixed Fraction, the answer

= 1\frac{7}{15}

Monique has $2.00 in change in her purse. If she has an equal number of nickels, dimes, and quarters, how many of
Sever21 [200]

Let the number of coins = X

A nickel is 0.05

A dime is 0.10

A quarter is 0.25

Set up an equation to add all the coins together to equal the total she has:

0.05x + 0.10x + 0.25x = 2.00

Simplify:

0.40x = 2.00

Divide both sides by 0.40

x = 2.00 / 0.40

x = 5

Check:

Nickels = 0.50 x 5 = 0.25

Dimes = 0.10 x 5 = 0.50

Quarters = 0.25 x 5 = 1.25

0.25 + 0.50 + 1.25 = 2.00

She has 5 of each coin.
