The new ratio will be
(5*1.4) : (7*1.5) : (8*1.75)
Or 7 : 10.5 : 14
To make them all whole numbers multiply them by 2 (because there is .5 after the 10)

Result: 14 : 21 : 28

What is 26.99 round to the nearest tenth
Arte-miy333 [17]
Salutations!

To round to the nearest tenth, you need know whether the number next to tenth place is greater than 5 or lesser than 5. If its greater than 5, you need to round up. If its lesser than 5, you need to round down. Now, in the number 26.99 9 is in the tenth place. The number next to 9 is greater than 5, so just add on to the ones place, making the tenth and hundredth place 0. Zero has no value so whether you add the zero or not, it does not matter.

<span>26.99 round to the nearest tenth </span>≈ 27

Hope I helped (:

Have a great day!

The sum of 12 and a number
(12 + n)

is no greater
< = 

then the sum of twice the number and 8
(2n +(-8)) = (2n - 8)

so we have :
(12 + n) < = (2n - 8)
