Try multiplying it we know that 8 times 10=80 so multiply 80 by 2, then 3 then 4 untill you get close to that number so 80 times 2=160 80 times 3=240 80 times 4=320 this is over so it is more than 30 8's but less than 40 8's so start from 320 subtract 293 from 320 320-293=27 divide 27 by 8 27/8=3 and 3/8 add that to 30
33 and 3/8 8's will fit
the teacher probably wants how many whole 8's can fit so get rid of the 3/8 and just put 33 8's
