2/5 plus 1/5 minus 3/10 is equal to 0.3 or 3/10
It is: 1.72 minus 0.05 = 1.67
There are 100 hundredths in each 1. There are 10 tenths in each 1. This means there are 10 hundredths in each tenth. Therefore, there are 5 tenths in 50 hundredths. 1 tenth = .1. 1 hundredth = .01. 50 hundredths = .50. Divide one tenth into 50 hundredths = .50/.1 = 5.
18.8
Since it is less than 5, the 3 hundredths rounds downward making the rounded number 1.0 to the nearest tenth.
9 ones + 1 tenth + 5 hundredths
3/5 = 6/10 so 6/10- 7/10 = -1/10 negative one tenth
Step 1. I look in the hundredths place. If I see a 5 or more I round up, otherwise down, to the next multiple of one tenth. Step 2. The number in the hundredths place is 5 so I know to round up. Step 3. The next higher multiple of one tenth is 21.4. That is the answer.
To round to the nearest tenth, look at the hundredths digit: if it is 5 or more round up otherwise round down. For 95.25 the hundredths digit is 5, so round up: 95.25 → 95.3 to the nearest tenth.

1/4-1/10= 5/20-2/20=3/20 [3/20]
