Question

1) 50÷20% 5÷50% 2) 2500÷135% 3000÷105%

Answer 1

1) 50÷20%=50:20/100=50*100/20=50*5=250

5÷50%=50:50/100=50*100/50=100

2) 2500÷135%=2500:135/100=2500*135/100=2500*20/27=50000/27 или 1851 23/27

3000÷105%=3000:105/100=3000*100/105=3000*20/21=1000*20/7=20000/7 или 2857 1/7

Answer 2

To solve these expressions, we need to understand the basic rules of arithmetic and percentages.

1. 50 ÷ 20% To divide by a percentage, we need to convert the percentage to its decimal form first. To convert 20% to decimal, we divide it by 100: 20% ÷ 100 = 0.20

Now, we can perform the division: 50 ÷ 0.20 = 250

So, 50 ÷ 20% equals 250.

Next, let's solve the second part:

5 ÷ 50% Again, we convert 50% to its decimal form: 50% ÷ 100 = 0.50

Now, we perform the division: 5 ÷ 0.50 = 10

So, 5 ÷ 50% equals 10.

2. 2500 ÷ 135% We convert 135% to its decimal form: 135% ÷ 100 = 1.35

Now, we perform the division: 2500 ÷ 1.35 ≈ 1851.85 (rounded to two decimal places)

So, 2500 ÷ 135% is approximately 1851.85.

Next, let's solve the second part:

3000 ÷ 105% Again, we convert 105% to its decimal form: 105% ÷ 100 = 1.05

Now, we perform the division: 3000 ÷ 1.05 ≈ 2857.14 (rounded to two decimal places)

So, 3000 ÷ 105% is approximately 2857.14.

To summarize:

1. 50 ÷ 20% = 250 5 ÷ 50% = 10

2. 2500 ÷ 135% ≈ 1851.85 3000 ÷ 105% ≈ 2857.14
