Answer:

The answers are already there

Step-by-step explanation:

If you want to know how to do it:

How to calculate percentage:

[From decimal]

Decimal x 100 = percentage

e.g. 0.2 x 100 = 20%

[From fraction]

Numerator / Denominator x 100 = percentage

top number / bottom number x 100 = percentage

e.g. 3/5 --> 3 / 5 x 100 = 0.6 x 100 = 60%

How to calculate decimal:

[From percentage]

Percentage / 100 = Decimal

e.g. 45% / 100 = 0.45

[From fraction]

Numerator / Denominator = Decimal

top number / bottom number = Decimal

e.g. 7/8 = 7 / 8 = 0.875

How to calculate fraction:

[From percentage]

Percentage number / 100 --> simplify

e.g. 38% --> 38/100 --> 19/50

[From decimal]

Decimal x 100 / 100 --> simplify

e.g. 0.75 --> 0.75 x 100 = 75 --> 75/100 --> 3/4

Hope this helps :)
