Question

Pedro mixes 3/4 teespoon of plant food into each gallong of water.How much teaspoons of plant food should Pedro mix into 5 gallons of water

Answer 1

we need to do 3/4x5. 3/4 is the same as 0.75. 0.75x5= 3.75. If you put that back into a fraction it is 3 and 3/4. This means pearl needs to mix 3 and 3/4 teaspoons of plant food into the water.

Answer 2

Work:

1 gallon of water requires 3/4 teaspoon of plant food, so multiply 3/4 by 5

3/4 × 5

Make 5 into a fraction

3/4 × 5/1

Multiply the denominator by the denominator and the numerator by the numerator

3 × 5 15
---- ---- = ------
4 × 1 4

15/4 is an improper fraction, so make it a mixed fraction

15/4 = 3 and 3/4

Answer:

Pedro should mix 15/4 teaspoons or 3 and 3/4 teaspoons of plant food into 5 gallons of water.
