Tonya's homework assignment has four problems a, b, c, d. Her teacher instructed her to simplify each expression and then find out its value. The value of a is 3/28, the value of b is 1/2, the value of c is 15/56 and the value of d is 1/15.

Each problem has two fractions. They are given below and should be simplified.

a) 2/7 × 3/8 = 1/7 × 3/4 = 3/28

b) 2/3 × 3/4 = 1/1 × 1/2 = 1/2

c) 3/7 × 5/8 = 15/56

d) 3/10 × 2/9 = 1/5 × 1/3 = 1/15

How can you tell if a point is a solution to a system of equations?
Anna35 [415]

Answer: you have to substitute them into the equation

Step-by-step explanation:

example: x = 2y - 6

lets say you test 4/5 so it would be 4 = 2(5) - 6

this equals 4 = 10 - 6 which is true

so that is how you test to see if the equation is right

remember the first number goes to "x" and the second one goes to y

hope this helps mark me brainliest if you can
