To work out 30% of 70
Work out 10% by dividing 70 by 10
This gives you 7
You then times this by 3 because
100%=70
10%=7
30%=21
It's simple after you understand the concept :)
To find the area in square feet, multiply the length by the width. For a space that is 70 feet by 30 feet, the area is 70 × 30 = 2,100 square feet.
To find the percent that a number, x, is out of another number, y, divide x by y and multiply by 100. So (21/30)*100 = 70, which means that 21 is 70% of 30.
The GCF of 30 and 70, evidently, is 10 (both end in 0). Therefore, the LCM is 30/10 * 70/10 * 10 = 3 * 7 * 10 = 210.
30 * 76 = 30 * (70 + 6) = 30*70 + 30 * 6 = 2100 + 180 = 228030 * 76 = 30 * (70 + 6) = 30*70 + 30 * 6 = 2100 + 180 = 228030 * 76 = 30 * (70 + 6) = 30*70 + 30 * 6 = 2100 + 180 = 228030 * 76 = 30 * (70 + 6) = 30*70 + 30 * 6 = 2100 + 180 = 2280
30% is 0.30 so, 0.30 x 70 = 2100 move the decimal to the left 2 times and get 21 and 21 is your answer!
70% of 30= 70% * 30= 0.7 * 30= 21
70% of 30= 70% * 30= 0.7 * 30= 21
To find 21 percent of a number, multiply the number by 0.21. In this instance, 0.21 x 70 = 14.7. Therefore, 21 percent of 70 is equal to 14.7.
The halfway point between two numbers is found by taking the average of the two numbers. In this case, the average of 30 and 70 is (30 + 70) / 2 = 100 / 2 = 50. Therefore, 50 is halfway between 30 and 70.

30+70 = 100
180 degrees in a triangle 180-70-30 = 80 The other angle is 80 degrees
