Answer:
savings = $360
spending = $160.
Step-by-step explanation:
saving : spending
9 : 4
total amount = $520
add the two parts in the ratio(9+4) to get the total parts.
9 + 4 = 13parts . so, 13 parts = 520.
what about 9 and 4?
13 = 520
9 = ?
9 × 520/13 = 360
4 × 520/13 = 160.
hope this helps.
It is the square of the input value
2/20 = 1/10 = 3/30 = 4/40
so 3 equivalent ratios can be 1/10 (or 1:10), 3/30 (or 3:30), 4/40 (or 4:40)
The answer is -6/7 or -0.857142
