how do you find 30% of 500 without calculator?
also how would you find 0.5% of 3200 without calculator?
is there a formula? i don't know where to start. i know 30/100 would be 3/10 and 0.5 is 1/2
Marie bought 8 pounds of applesbfor 0.82 per pound and paid for them with a ten dollar bill. How much should she get back in change
surely you can do 3*5
now just move the decimal point as needed.
.5% = 1/200
I'm sure you can do 3200/200
.5 is 1/2, but .5% is not.
10.00 - 8*0.82 = ?
To find 30% of 500 without a calculator, you can follow these steps:
1. Convert 30% to a decimal by dividing it by 100: 30 ÷ 100 = 0.3
2. Multiply the decimal value by 500: 0.3 × 500 = 150
Therefore, 30% of 500 is 150.
To find 0.5% of 3200 without a calculator, you can use a similar approach:
1. Convert 0.5% to a decimal by dividing it by 100: 0.5 ÷ 100 = 0.005
2. Multiply the decimal value by 3200: 0.005 × 3200 = 16
Therefore, 0.5% of 3200 is 16.
There isn't necessarily a specific formula for these calculations, but it's helpful to understand the concept of percentages and how to convert them to decimals before performing the multiplication.
