What's the nearest ten to the number 907

The answer would be 910 because numbers 1-4 round down to the nearest tenth and numbers 5-9 round up to the nearest tenth. This number ends in 7, so we would round up to the nearest tenth. This would make the correct answer 910 

The nearest ten to 907 is 910. For future reference, any number that is equal to or greater that 5 will round up, adding one to the next largest spot. For example if I took  835, it would round to 840. But if the number is less than 5, you want to round down. Say I had 392, it would round to 390.
