Answer: 54
Step-by-step explanation:
First we add 17 plus 18 to dins total number of students I got 35
Then we make ratio
3/35
So we know we have total number of 630 kids then we make a ratio with no teacher so x
X/630
Lin both together then done ☑️
Let's call this unknown number, x.
So then we can put together the equation using the information from the question:
Then we start by distributing this 10 to both the and the 6:
Then we subtract 60 on both sides:
Then we divide both sides by 5 to solve for x:
or
We use BODMAS in the following sequence
B - bracket
O - of
D - Divide
M - multiply
A - addition
S - subtract
so firstly we have to solve bracket then of then we have to do divide then we have to solve multiply the. we have to solve add and at last to we have to solve subtract
