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)
