Answer:

Step-by-step explanation:
Hey there!
Let's plug in our values:
3(-2) - 4(1) =
-6-4 =
-10.
Hope this helps!
Firstly, write out as a number, using a few repeats of the decimal. If we multiply this number by 10 it will give a different number with the same digit recurring. When two digits recur multiply by 100 so that the recurring digits after the decimal point keep the same place value.
1/5 of a metre. 0.2m. 20cm. However you like to write it :)
This is because 3/5 is being divided by 3. So a third of 3/5 is 1/5, just as a third of 3 is 1.
Also, if you change it decimals, you get 0.6m ÷ 3 = 0.2m. You can then change it to cm if you like. 0.2m, 20cm, 1/5 of a metre. They're all the same thing and equally acceptable as an answer.
Hope I helped :)
