10) Some money is shared between Neidy and Otto in the ratio 2:3 respectively. If Otto received $240, find; a) total amount of money
b) Neidy's share
c) fraction Otto received.

a) $400

b) $160

c) 3/5

Step-by-step explanation:

Neidy : Otto = 2 : 3

2 + 3 = 5

Therefore, Neidy received 2/5 of the money and Otto received 3/5 of the money.

If 240 = 3/5, then 1/5 = 240 ÷ 3 = 80

⇒ Neidy = 2/5 = 80 x 2 = 160

⇒ Otto = 3/5 = 80 x 3 = 240

a) Total amount of money = 160 + 240 = $400

b) Neidy's share: $160

c) fraction Otto received = 3/5

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
