Step-by-step explanation:
I'm sorry if my terminology isn't correct because I've learnt it slightly differently, but what I'm assuming is this:
For A, you can rewrite the integers as 28-15+22 as a + and a - next to each other result in a subtraction.
For B, you simply do 15+22 is 37 and 28-37 is -9 due to BIDMAS (or PEDMAS if you're American).
3 hearts
4 triangle
H:T
3:4
So, ratio of hearts to triangles in simplest form is 3:4
(we can't simplify any further - HCF of 3 & 4 is 1)
Hope this helps!
The answer to your question is,
A) 500. The only way it would be more than 500 is for the tens place to be 5 or over. :)
