Please answer all questions
Answers
Step-by-step explanation:
(a) yes , because 40x45= 120 x15
similarly e only is in proportion
hence answer is only a and e is in proportion and ith are not in proportion .
pls mark me as brainliest
Answer:
Step-by-step explanation:
a) 40, 120, 15, 45
Product of extremes = Product of means
40 × 45 = 120 × 15
1800 = 1800
Hence, the terms are in proportion.
b) 121, 33, 96, 6
Product of extremes = Product of means
121 × 6 = 33 × 96
726 ≠ 3168
Hence, the given terms are not in proportion.
c) 28, 24, 48, 36
Product of extremes = Product of means
28 × 36 = 24 × 48
1008 ≠ 1152
Hence, the given terms are not in proportion.
d) 70, 210, 32, 48
Product of extremes = Product of means
70 × 48 = 210 × 32
3360 ≠ 6720
Hence, the given terms are not in proportion.
e) 8, 12, 4, 6
Product of extremes = Product of means
8 × 6 = 12 × 4
48 = 48
Hence, the given terms are in proportion.
f) 33, 44, 75, 100
Product of extremes = Product of means
33 × 100 = 44 × 75
3300 = 3300
Hence, the given terms are in proportion.
