How do you do equations with rational number​

1)if it's a decimal than u don't have to do much just do it normally.

2)if it a fraction, turn it into a decimal and do it. but u can do it as a fraction too.

3)if it's a mixed number turn it into decimal or improper fraction and do what ur suppose to do.

*it's you choice. chose either decimal or fraction. it's ur choice. do wuts easier for u.

P= 2

T=6

3) 252$

Step-by-step explanation:

1) set up your equation 3/8p=6/8 then divide 3/8 from both sides (remember when you divide fractions you would multiply by the reciprocal so 3/8 x 8/6. Also make sure you simplify)

2) Do the same here. 38/7 divided by 19/21

3) Turn the fraction into an improper fraction then multiply 126 by that amount (3/6)
