Answer: 64 ; $28
Step-by-step explanation:
A. Billy collected 256 conks but lost ¾ of them on his way to school through a hole in his bag. When he arrived at school how many conks did Billy had left?
Number of conks collected by Billy = 256
Fraction lost = 3/4
Amount lost = 3/4 × 256 = 192
Number of conks Billy has left will be:
= 256 - 192
= 64
B. Skateboards cost €36 each in my local store. The shopkeeper says if I buy one I can buy another for only 7/9 of the normal price. How much would a second skateboard cost?

= 7/9 × $36
= 7 × $4
= $28
Answer:
value we donnot know so we try to find it by equations
11.5 cm
33/2 = 16.5
16.5 - 5 = 11.5
Double Check
11.5 + 21.5 = 33
