If the starting ratio was 2 laptops for every 3 desktops sold, and there are now 18 desktops sold, the original amount of desktops multiplied by 6, so the original number of laptops must also multiply by 6. 6*2 = 12 thus there are now 12 laptops sold.
Answer:
5/6
Step-by-step explanation:
1/2 + 1/4 + 1/12 =
The LCD is 12.
= 6/12 + 3/12 + 1/12
= 10/12
= 5/6
Answer:
1560
Step-by-step explanation:
First (2 1/2)/(1/4) = (5/2)(4) = 20/2 = 10
Next, 3/(1/4) = 3(4) = 12
Lastly, (3 1/4)/(1/4) = (13/4) x 4 = 52/4 = 13
This means we need 10 rows of 12, 13 high. 10(12)(13) = 1560 cubes.
Another way is to multiply 2 1/2 x 3 x 3 1/4 = 5/2 x 3 x 13/4 = 195/8
A 1/4 inch cube is 1/4 x 1/4 x 1/4 for a volume of 1/64
(195/8)/(1/64) = (195/8)(64) = 1560 cubes.
