Question

418 attend a concert. There are 98 fewer boys than girls. How many boys are there and how many girls?

Answer 1

160 boys and 258 girls . 258+ 160= 418. 160+98 = 258. First step: 418-98= 320 divided by 2 = 160 160 boys 160+98=258 girls.

Answer 2

418 divide by 2: gives you the exact half number 209

then you subtract 98 from 209 for guys

and you add 98 to 209 for girls

effectively giving you:
guys: 111
girls:307
