okay, so basically it’s the ratio of damaged to undamaged toys. which means that damaged is ‘3’ and undamaged is ‘17’. what i would do, is that i would:
17+3=20
200/20=10
so, ‘1’ refers to 10 toys. therefore we multiply the amount of undamaged toys by 10 which would get u the answer
10x17=170
which, equals to 170 undamaged toys.
i hope this helped u :)
