Answer» Answer: i will answer Step-by-step explanation: question 1:- in (a) both ratios are proportional to each other in (b) both ratios are not proportional to each other question 2:- in (a) product of means is EQUALS to product of extremes 45x=1125 x=1125/45 =25 in (b) product of means is equals to product of extremes x^2=196 x=14 question 3:- in (a) a:b and a/b will have same meaning so (2/15)/(7/45) finally if you solve you get 6/7 or 6:7 in(b) follow same method mentioned in answer question 4:- convert all into either minutes or SECONDS in (a) and grams or kgs in(b) question 5:- for 12m COST is 720 for 1M cost is 720/12 60 for 8m 60(8) 480

Answer:

i will answer

Step-by-step explanation:

question 1:-

in (a) both ratios are proportional to each other

in (b) both ratios are not proportional to each other

question 2:-

in (a) product of means is EQUALS to product of extremes

45x=1125

x=1125/45

=25

in (b) product of means is equals to product of extremes

x^2=196

x=14

question 3:-

in (a)

a:b and a/b will have same meaning

so (2/15)/(7/45)

finally if you solve you get 6/7 or 6:7

in(b) follow same method mentioned in answer

question 4:-

convert all into either minutes or SECONDS in (a)

and grams or kgs in(b)

question 5:-

for 12m COST is 720

for 1M cost is

720/12

for 8m

60(8)

480
