There are 165 counters in a bag. Each counter is either black or white. There are twice as many black counters as white counters in the bag. Martine takes 40% of the black counters from the bag.

Work out the ratio of the number of black counters to the number of white counters now in the bag.
Give your ratio in its simplest form.

6:5

let the white counter be x

2x + x = 165

divide both sides by 3

there are 55 white counters in the bag

165-55=110

OR

2x= 165

divide both sides by 2

x= 110

40%= 40/100×110

= 44.

▪︎ there would be 66 black and 55 white counters in the bag.

• the answer is 6:5

step-by-step explanation:

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
