Help me with this one. I’m stuck with it since an hour and a bit more.
irina [24]

Answer:

1) 5 : 7 : 8.75

2) Happy = 168 .    Juma = 210

3) Rima = 17800 .     Happy = 24920 .    Juma = 31150

Step-by-step explanation:

1) 5 : 7 : 8.75

Ratio Rima to Happy = 5:7

Ratio Happy to Juma = 4:5

7/4 = 1.75

1.75 x 5 = 8.75

Ratio = 5 : 7 : 8.75

2) Happy = 168 .     Juma = 210

Ratio = 5 : 7 : 8.5

120 / 5 = 24

Happy = 24 x 7 = 168

Juma = 24 x 8.75 = 210

3)17800 : 24920 : 31150

5 + 7 + 8.75 = 20.75

73870 / 20.75 = 3560

3560 * 5 = 17800 = Rima

3560 * 7 = 24920 = Happy

3560 * 8.75 = 31150 = Juma

If my answer is incorrect, pls correct me!

Horatio wrote the multiplication facts for 8. which digit will not be in the ones place of the products?
dangina [55]

Answer:

Odd digits like 1, 3, 5, 7, and 9will not be at ones place of the products.

Step-by-step explanation:

If we look at multiplication facts of 8 we can see that,

8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96 etc

We can see that at the ones place, only even digits show up, like

0, 2, 4, 6, 8

But there is no odd digit at ones place.

So if Horation wrote the multiplication facts for 8, none of the odd digits will be there at ones place. Those digits include, 1, 3, 5, 7 and 9.
