Answer: I wow I don't know about the whole page but (Question 2 ) 24 multiplied by b equals number of mangoes in b boxes
Step-by-step explanation: I hope this makes sense.
b can be replaced with any number you can create a number sentence by plugging in 4 for example 24 * 4 = 96 so there is a total of 96 mangoes if b= 4
If I am reading this correctly...the ratio would be
Austalia championships: the total of countries championships
for example australia = 18 and the other countries have 300
ratio would be 18:300 or 18/300
Then simplify 3:50 or 3/50
Hope this was helpful!
