- 4+ 7 : 200 7/200 0.035 3.5%
Step-by-step explanation:
I'll use row 3 as an example to show you how to do all these.
# siblings ratio fraction decimal percent
- 3 <u> </u> <u> </u> 0.24 <u> </u>
<u>To find fraction</u>
put number over 100 and just simplify as much as you can.
24/100 = 12/50 = 6/25
<u>To find ratio</u>
ratios are the same as fractions, but instead of the fraction bar or slash, you have a colon.
this one would look like 6 : 25 as a ratio.
<u>To find decimal</u>
DIVIDE the fraction or ratio (using a calculator if allowed, or by hand otherwise)
6/25 = 0.24
<u>To find percent</u>
take the decimal once you find it, and move the decimal point to the right by 2 digits. That's the percent.
0.24 ==> 24%

5 and 20
m = √(5 * 20) =
m = √100
m = 10
3 and 12
m = √(3 * 12)
m = √36
m = 6
do the rest the same way
Answer:
Total Weight of Bowl W = 340 + (12.5T) grams
Step-by-step explanation:
Given
Weight of Ceramic Bowl = 340 grams
1 table Spoon of Sugar Weighs = 12.5 grams
So T table Spoon of Sugar Weighs = 12.5T
Total Weight of Bowl W = Weight of Ceramic Bowl + Weighs of T table Spoon of Sugar Weighs
Total Weight of Bowl W = 340+ (12.5T)grams
The three types of boots are sold in the ratio 6:2:3.
This ratio may be written as 6x:2x:3x where x is a variable.
When 24 boots are sold, then
6x + 2x + 3x = 24
11x = 24
x = 24/11 = 2.18
Because we do not have fractional boots, x = 2.
Total boots sold = 6*2 + 2*2 + 3*2 = 12 + 4 + 6 = 22
Answer: 22
