Answer:
(2/4)/(4/4) = 0.5 or 2/4
Step-by-step explanation:
1.50 5/9(122-32)=5/9(90)= 50
Answer:
remove the bracket on the other side by multiplying 180 by (2-n)
subtract 360 from 1260 to remain with -180n on the other side
divide both sides by -180n
then n become -5
80x40=3200 total marks
30x75=2250 total girls marks
3200-2250=950 total boys marks
40-30=10 number of boys
950/10=95 man mark for boys
