Answer:
10.5 : 12 : 13.5
Step-by-step explanation:
12 ÷ 8 = 1.5 (multiply this by all of the known numbers
8 x 1.5 = 12
7 x 1.5 = 10.5
9 x 1.5 = 13.5
Answer:
7 : 8 : 9 = 21/2 : 12 : 27/7
Step-by-step explanation:
GIVEN ; 7 : 8 : 9 = ? : 12 : ?
7/24 : 8/24 : 9:24 = ? : 12/x : ?
8/24 = 12/x
x = 12 × 24/8
x = 36
therefore the other two ratio's are
7/24 = ?/36
? = 36 × 7/24
? = 21/2
and
9/24 = ?/36
? = 36 × 9/24
? = 27/2
im not quite confident with this answer, but i hope it helps!
