Express as metres using decimals.(a) 15 cm (b) 6 cm (c) 2m 45 cm(d) 9 m 7 cm (e) 419 cm

To convert the given measurements into meters using decimals, we need to remember the following conversion:

1 meter = 100 centimeters.

To convert centimeters to meters, divide the number of centimeters by 100.

Now, let's solve each part:

(a) 15 cm: 15 cm = 15 ÷ 100 = 0.15 m

(b) 6 cm: 6 cm = 6 ÷ 100 = 0.06 m

(c) 2 m 45 cm: First, convert 45 cm to meters: 45 cm = 45 ÷ 100 = 0.45 m Now, add the meters: 2 m + 0.45 m = 2.45 m

(d) 9 m 7 cm: First, convert 7 cm to meters: 7 cm = 7 ÷ 100 = 0.07 m Now, add the meters: 9 m + 0.07 m = 9.07 m

(e) 419 cm: 419 cm = 419 ÷ 100 = 4.19 m

So the results are:

(a) 0.15 m (b) 0.06 m (c) 2.45 m (d) 9.07 m (e) 4.19 m
