1 and a half sandwich each or 1-1/2 or 1.5
This is a confusing question but I'm guessing an equivalent name for 57 is fifty-seven.
We can use ratios and the cross-multiply-divide to find this.
The ratio 21:5 is avaliable via the question. We then need to compare that to the ratio x:100, the 100 being the percent and the x being the number of airplane parts.
21/5 = x/100
We can then solve for x to find the number of airplane parts. First we multiply by 100 on both sides to get 2100/5 = x. Therefore x = 420 and there are 420 airplane parts.
Step-by-step explanation:
dividing every number by 10.
100:15:50
dividing every number by 5.
20:3:10.
this is the lowest term.
hope this helps you.
