Answer:
315
Step-by-step explanation:
1. This is not a scale rectangle and it angers me.
2. All you have to do is draw proportions.
5x7=35
15x21=315
Youll notice that 5x3=15 and 7x3=21 so it’s just proportions!
Answer:
17.52
Step-by-step explanation:
literally 11.6 x 1.51 and then round to hundredth place
30 is 20% of 150
Working out percentage problems of the form "30 is 20 percent of what number?"
We have, 20% × x = 30
or,
20/100 × x = 30
Multiplying both sides by 100 and dividing both sides by 20,
we have x = 30 × 100/20
x = 150
If you are using a calculator, simply enter 30×100÷20, which will give you the answer.
