Just draw like the 2 hundredths, 4 tens, and 6 ones
And then draw 7 tens and 8 ones
12/13 I believe :) hope it helps
For Question 1:
angle CAB, angle ABC, angle BCA
Question 2: angle BCD
She would get £2.50
4 times 2 is 8
2 times 3 is 6
0.7 times 5 is 3.5
Add them together
Minus it from 20
It equals £2.50
