Number 4. will be a. because if you do 7*9=63*10=630.
Answer:
A. 2
B. 10/3
C. 8/3
D. 2/3
Step-by-step explanation: put the whole #and make it into a fraction like this e.g.
6/1 • 1/3 = 6/3 simplifies to 2
Write the equation: x + 42 + 30 = 131
Combine like terms: x + 72 = 131
Subtract 72 from both sides: x = 59
Step-by-step explanation:
Sam's Income = ₹9000
Lisa's Income = ₹6000
Total earning = Sam's Income + Lisa's Income = ₹15000
Now,
Ratio of Sam's Income to the Total earning = ₹9000/₹15000 = 3:5
Ratio of Lisa's Income to Sam's earning = ₹6000/₹9000 = 2:3
In the sequence, a,b,c,d... the common ratio is b/a or c/b or d/c etc
so
common ratio in 225 and 49 and 9 is
49/225 or 9/45=1/5
the common ratio is 1/5
