Rounding Decimals

U03_L1_T2_we2 Rounding Decimals

Round 9.564, or nine and
five hundred sixty-four

thousandths, to the
nearest tenth.

So let me write it a little
bit larger, 9.564.

And we need to round to
the nearest tenth.

So what's the tenth place?

The tenths place
is right here.

This right here represents
5 tenths.

This is the ones place, this is
the tenths place, this is

the hundredths place,
and this is the

thousandths place right here.

So we need to round to
the nearest tenth.

So if we round up,
this will be 9.6.

If we round down, this
will be 9.5.

And just like regular rounding,
when we're not

dealing with decimals, you move
to one spot, or you look

at one place to the right or one
place lower, I guess, and

you say is that 5 or larger?

If it is, you round up, if
it isn't, you round down.

6 is definitely 5 or larger,
so we want to round up.

So this 9.564 becomes 9.6,
or we can call this

nine and six tenths.

And then we're done!
