Answer 2

Answer: 0.78 and 39/50

Step-by-step explanation:

What we know:

• We need to find 78% as a fraction and decimal

How to solve:

The decimal is easy enough, and then the fraction can be found from there. D will represent decimal, p will represent percentage, and F will represent fraction.

Process:

Decimal

Set up equation D = p / 100

Substitute D = 78% / 100

Simplify D = 0.78%

Remove % sign D = 0.78

Fraction

Set up equation F = p / 100

Substitute F = 78% / 100

Remove % sign F = 78 / 100

Simplify if needed F = /2 /2

F = 39 / 50

Solution: 0.78 and 39/50

Check:

Multiply the decimal by 100 to check the decimal

0.78 x 100 = 78; 78%

Divide the fraction to check the fraction

39/50 = 0.78; see above
