Answer:
3/5
Step-by-step explanation:
3/5 of 1/4 is 3/5
or 3/5*1/4= 3/5
1/3
add all of the totals including the missing pair
we now have 24
7+1 is 8
24 minus 8 is 16
24 can be split into 2 groups of 8
and we have 2/3 left. which makes our solution 1/3
4,ooo,ooo mm equal 4km
6/10
2 × 3 = 6
5 × 2 = 10
OR
6/10 = 3/5
3a+9=54
3a+9-9=54-9
3a= 45
a=15
Check answer:
3(15)+9=54
54=54
Answer is a=15
