Answer:
85% decrease
Step-by-step explanation:
The percentage change is the change fraction multiplied by 100%.
percent change = change / original × 100%
= (3 -20)/20 × 100%
= -17/20 × 100% = -85%
A decrease from £20 to £3 is a change of -85%.
Answer:
64

16/100 = x / 400

x = 6400 / 100

Answer:
1%
Step-by-step explanation:
We need our two numbers to have the same units. Since one number is in cents and the other is in dollars, we should change one of them. It could be either one.
Both numbers in cents:
50/4000
OR, both numbers in dollars:
.50/40.00
Either of these will work. Divide, you will get a decimal answer. Then multiply by 100 to change to a percent.
50÷4000 (OR .5/40)
= 0.0125
times by 100
0.0125 × 100
= 1.25% but the directions said to round to the nearest whole number, that's 1%
