Answer: Using mental math to add with decimals is like using mental math to add whole numbers because the actual thing is we are adding the place values in both the cases and they different as in case of whole numbers we start from the ones place but in case of decimal numbers we first separate it into whole numbers and decimals to add by using mental math separately, after solving the sum we write both parts together and that is the answer.
For example to add 4.50+9.20
Take after decimal portion separately 0.50+0.20=0.70
and 4+9=13
write together it becomes 13.70.
so 4.50+9.20=13.70.
It has to do with equation of a straight line and I hope it helps

Answer:
1/4
Step-by-step explanation:
There are 8 times 84s that are present in 672.
When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.
We need to find how many 84s are present in 672
We will simply divide the 84 by 672.
That is;
672/ 84
= 336/42
= 168/21
= 8
Hence, there are 8 times 84s that are present in 672.
