Change to a whole number or mixed number 12/7

1 and 5/7

Step-by-step explanation: To write an improper fraction as a mixed number,

divide the denominator into the numerator.

So here, we have 7 divided into 12.

7 divides into 12 one time, 1 × 7 is 7, and 12 - 7 is 5.

So 7 divides into 12 one time with a remainder of 5.

So we have 1 whole and 5 out of 7 parts or 1 and 5/7.

So the improper fraction 12/7 can be written

as the mixed number 1 and 5/7.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

the answer is 1/4
