Answer:

67.5

Step-by-step explanation:

I've learned this multiple ways but in my opinion this is the easiest. Just times everything together so, 40 x 2.5 x 1.2 which equals 135 and then divide 135 by 2 which equals your answer of 67.5 which is rounded to the nearestt tenth already.

Mortar is made by mixing cement, sand and quicklime in the ration 1:2:3
timurjin [86]

Answer with step-by-step explanation:

If the ratio for the ingredients is 1:2:3, then the total would be 6. If so, we have to divide 2.1 by 6, which is 0.35. Now, you need to multiply 0.35 to the according ingredient amounts.

Cement: 1 x 0.35 = 0.35

Sand: 2 x 0.35 = 0.70

Quicklime: 3 x 0.35 = 1.05

If you add it up, you will get 2.1, which is the volume.

Hope this helped! (brainliest please)
