For #1 I think maybe 5 qts
1. We assume, that the number 40 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 40, so we can write it down as 100%=40.
4. We know, that x% equals 21 of the output value, so we can write it down as x%=21.
5. Now we have two simple equations:
1) 100%=40
2) x%=21
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=40/21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 21 is what percent of 40
100%/x%=40/21
(100/x)*x=(40/21)*x - we multiply both sides of the equation by x
100=1.90476190476*x - we divide both sides of the equation by (1.90476190476) to get x
100/1.90476190476=x
52.5=x
x=52.5
now we have:
21 is 52.5% of 40
the ratio that compares a number to 100 is called percent
We need to find the products of 6×2,194 using partial products .
2,194 could be written in expended form as,
2194 = 2000 + 100 + 90 + 4.
Now, we need to multiply each of those number by 6 what we got after expanding.
2000 × 6 = 12000
100 × 6 = 600
90 × 6 = 540.
4 × 6 = 24.
Now, we can add all those products.
12000 + 600 + 540 + 24
= 13164.
<h3>Therefore, 6×2,194 = 13164.</h3>
