Subject: Re: grade 5 math homework
my name is Bonnie I am having trouble assisting my son with his grade 5 math
we are totally confused can someone help
There can be many answers to such a question but I suspect that the teacher wants you to notice that all the outputs are multiples of 10 'one higher' than the number itself.
12 --> 20
24 --> 30
39 --> 40
so I would say that
87 --> 90
Hope this helps.
