Question

4040÷21 answer with methord

Answer 1

Answer:

Hey mate here is your answer

Step-by-step explanation:

Method 1: Diagonal multiplication to calculate "21 is 4040 percent of what number".

As given: For 4040, our answer will be 100

Assume: For 21, our answer will be X

4040*X = 100*21 (In Steps 1 and 2 see colored text; Diagonal multiplications will always be equal)

X = 100*21/4040 = 2100/4040 = 0.519802

21 is 4040 percent of 0.519802

Method 2: Same side division to calculate "21 is 4040 percent of what number".

As given: For 4040, our answer will be 100

Assume: For 21, our answer will be X

100/x = 4040/21 (In Step 1 and 2, see colored text; Same side divisions will always be equal)

100/X = 4040/21 or x/100 = 21/4040

X = 21*100/21 = 2100/4040 = 0.519802

21 is 4040 percent of 0.519802
