Bought the same number of Guppies and only Hank bought 2 additional Platies. Thus, let’s subtract the total of Hank and Martha
=> 18.33 – 13. 95 = 4.38
Thus, Hank paid an additional of 4.34 for 2 platies. Let’s divide to get the price of platies
=> 4.34 / 2 = = 2.19 (price of platies each.)
Let’s solve for price of guppies
=> 13.95 – 4.34 = 9.61
=> 9.61 / 3 = 3.20 (Price of guppies each.)
Answer:
He is correct
Step-by-step explanation:
12=100%

12 divided by 3 is 4
100 divided by 4 is 25
100 + 25 = 125
The answer to 2/3 x 1/2 is 2/6 or 1/3
To find the decimal form you just have to divide 1 by 3
You get 0.3333333333........ repeating
So just put a repeating bar over 3 in 0.3
