Three tens (3) plus five tens (5) would be eight tens (8), which is eighty (80).
I don't know if this is the correct answer nor if this is how you are supposed to answer it, but it's my guess.

What percentage of 340 is 425?
beks73 [17]

Answer:

125%

Step-by-step explanation:

1. Set up the equation

425/340 = x/100

(percentages are out of 100 so this equation means 425 out of 340 is equal to a number out of 100)

2. Cross multiply

340x = 42500

3. Solve for x

x = 125
