Roger has 2 1/2 cups of peanut butter. A recipe for a loaf of bread requires 3/4 cups of butter. How many loaves of bread can he

Sergio [31]

Answer:

3 loaves of bread

Step-by-step explanation:

We must divide $2\frac12$ by $\frac34$ and take an integer part of this dividing.

$2\frac12:\frac34=\frac52:\frac34=\frac52\cdot\frac43=\frac{20}{6}=\frac{10}3=3\frac13$

The integer part of a mixed fraction $3\frac13$ is 3, and this is the answer.

Answer:

one tin of cheese $23

one tin of caramel $27

Step-by-step explanation:

let 'x' = cost of cheese tin

let 'y' = cost of caramel tin

10x + 8y = 446

22x + 11y = 803

i multiplied the first equation by -11 and the second by 8 to eliminate the 'y' terms

-110x - 88y = -4906

+ <u>176x + 88y = 6424</u>

66x = 1518

x = 1518 / 66

x = 23

find 'y': 10(23) + 8y = 446

230 + 8y = 446

8y = 216

y = 27
