I think you just put 20 in the blank in order for it to equal
twenty eight plus the product of five and a number
28 + 5n
28 + 5(4.2)
28 + 21
49
Hello!
Decimals used to confuse me a lot! :D
When a question asks to round the decimal to the "nearest tenth", it simply means to round it to one decimal place.
6.7086 would be rounded to 6.7 if we round it to the nearest tenth. See, the 7 is in one place after the decimal point.
The best way to understand decimal places, in my opinion, is to search up a tenths, hundredths, thousandths, etc. chart. Hope this gave you a better understanding of decimal places!
