You multiply it with the same number you use for the denominator.
in this case 3/4 and 7/10
you find the LCM of the denominator is 20
so for 4 to become 20 you multiply by 5 then for the numerator 3 also multiply by 5, so you get 15/20
its the same also with 7/10, you multiply both the numerator and the denominator by 2 and get 14/20
hope it help... :)
8 . You round 31.9 to 32 then divide it by 4 which gives you 8
This theorem says that the exterior angle is equal to the sum of its remote interior angles. In other words, 140 = 2x + x + 2. 140 = 3x + 2 and 138 = 3x. Therefore, x = 46. Multiply it by 2 to get angle B is 92 degrees.
Answer:
4. 1,5, 25, 125,_
Step-by-step explanation:
First lets double the dimensions:
5cm becomes 10cm
4cm becomes 8cm
3cm becomes 6cm
To find the volume, we multiply all the new numbers together:
10 x 8 x 6 = 480cm³
