This is my maths work for the week.
Mr Burt has $1000 in the maths budget at the start of the year.
He starts by purchasing 650 math books, at $0.30 each. His total spend is: 195, 650x3=1950/3=195
How much does he have left? 805
Next he spends $167.70 on rulers and protractors
800-162.70=642.30
How much is left now?
642.30
Then he purchases 5 text books, which cost $26.50 each. The 5 textbooks cost:
125+7.50=132.50 642.30-132.50=509.80
How much does he have left?
509.80
Finally he spends $6.70 on stickers.
503.10
How much does he have left?
503.10
What is the best strategy for these problems?
4 - 0.768 =4-0.700=3.300-0.60=3.260-0.8= 3.254
15 - 5.67 =15-5.6=9.4-.07=9.33
2.50 - 1.75 =0.75
5 - 0.654 =4.456
