Step-by-step explanation:
i just know it and ive done it before bro.
Answer:
Step-by-step explanation:
1).
= 2 : 3
2). 6 : 4 =
=
6 : 4 = 3 : 2
3).
= 1 : 3
4). 12 : 8 =
=
= 3 : 2
And = 3:2
Therefore, 12 : 8 =
5).
= 7 : 4
6). 4 : 10 =
=
Therefore, equivalent ratios are,
a). 2 : 3 =
b). 3 : 2 = 6 to 4
c). = 1 : 3
d). 18 to 12 = 12 to 8
e).
f).
9x10^7
10x10=100x10=1,000
1,000x10=10,000
10,000x10=100,000
100,000x10=1,000,000
1,000,000x10=10,000,000
10,000,000x9=90,000,000
3x10^3
10x10=100x10=1,000
1,000x3=3,000
90,000,000/3,000=30,000
So 9x10^7 is 30,000x larger than 3x10^3
hope it helps!
