If matt and jan each make 10 gallons of punch how many more gallons of orange juce would jan use yhan matt

Can you give the whole question please?

rounding to the nearest whole number basically means rounding the decimals so they disappear e.g. 11.5 would round up to 12 because 5+ rounds upwards and below 4 rounds down so say it was 15.34 it would round down so it would be 15.
I hope this helps ;)
