Just multiply by 20
A and E
When you multiply any equation with a decimal you add that many decimal places in the end.
Ex: If you multiply 4.12×5.8 there will be 3 decimal places in the product because 4.12 had 2 decimal places and 5.8 had 1 decimal place and 2+1=3.
The only exception is when you multiply a decimal with a number that ends with a 0 and is not a decimal like 10, 20, 30, 100, 1000, etc. If this is the case then put the decimal where it would have been and then move it right the same number as you have 0s.
Ex: 1000× 5.82 would have been 5.82000*, but becomes 5,820.00*, which really is 5,820*.
*continuous 0s after a decimal is unnecessary and will probably make you lose points on a test, but I was trying to prove a point

Answer: 2.7 hours
Step-by-step explanation:
Hi, to answer this question we simply have to calculate the amount of time that takes making one batch of dinner rolls, by adding the individual times of, kneading, resting and baking.
