Answer:
minus x minus y and you get your answer
13 5/9 - 8 1/6
= [ (13 * 9) + 5)/9 ] - [ (8*6)+1)/6 ]
= 122/9 - 49/6
= 122*6 - (49*9) / (9*6)
= ( 732 - 441 ) / 54

Answer:
<em>Option </em><em>3</em>
Step-by-step explanation:
Rewriting input as fractions if necessary:
3/8, 3/20
For the denominators (8, 20) the least common multiple (LCM) is 40.
LCM(8, 20)
Therefore, the least common denominator (LCD) is 40.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
3/8 = 3/8 × 5/5 = 15/40
3/20 = 3/20 × 2/2 = 6/40
Exponential
The first year, he would earn 8% interest on the $400 deposited, so he'd have $432. The next year, he would earn 8% interest on the interest earned the previous year in addition to the amount deposited, so he'd have $466.56.
His bank balance would follow the compound interest equation which is exponential.
= 400 × 1.08^t
where t is the number of years since the deposit
