200 x 20% = 200 x 0.20 = 40
0.4 x 200 = 0.4 x 10 x 20 = 4 x 20 = 80
10. Let us assume x is the number. x * (20/100) = 2 x * 20 = 200 x = 200/20 = 10 2 is 20% of 10.
first, convert everything to cm: 200 cm x 200 cm x 20 cm (m = 100 cm, dm = 10 cm) then: 200 x 200 x 20 = 800,000 cm3 (or 800 dm3 or 0.8 m3)
20 x 05 = 100
10 x 20 = 200
200 + 20% = 200 x (1 + (20/100)) = 200 x 1.2 = 240
200 x 20% = 200 x 0.20 = 40
10
x/100 * 20 = 40 x/100 = 2 x = 200%
200 x .05 = 10; 200 - 10 = 190
two thousand 0.1 = 0.05 x 2 1 = 0.05 x 20 10 = 0.05 x 200 100 = 0.05 x 2,000
0.4 x 200 = 0.4 x 10 x 20 = 4 x 20 = 80
10. Let us assume x is the number. x * (20/100) = 2 x * 20 = 200 x = 200/20 = 10 2 is 20% of 10.
200 and 20. 200 is an integer. 20 is an integer. 200 x 20 = 4000.
20 percent of 200 = 20/100 x 200 = 4000/100 = 40
first, convert everything to cm: 200 cm x 200 cm x 20 cm (m = 100 cm, dm = 10 cm) then: 200 x 200 x 20 = 800,000 cm3 (or 800 dm3 or 0.8 m3)
