Answer:
1. a = (18 x 60)/24
a = 1080/24
a = 45
2. r = (52 x 4)/26
r = 208/26
r = 8
3. b = (36 x 1 )/4
b = 36/4
b = 9
4. m = (105 x 3 )/ 45
m = 315/45
m = 7
5. d = (12 x 75) /20
d = 900/20
d = 45
6. o = (12 x 50)/10
o = 600/10
o = 60
7. i = (1/2 x 10)/5
i = 5/5
i = 1
8. u = (4 1/2 x 81)/13 1/2
u = 364.5/13.5
u = 27
9. n = (3.6 x 14.4)/7.2
n = 51.84/7.2
n = 7.2
10. j = (4.8 x 13.6)/9.6
j = 65.28/9.6
j = 6.8
pa brainliest naman! hope it helps :)
