Frank had 25 meters of string. He cut off 480 centimeters that became tangled then used 98 centimeters to tie ul some tree branches. How many meters of string did Frank have left?

3 answers

480 cm = 4.8 m

98 cm = 0.98 m

4.8 + 0.98 = 5.78

25 - 5.78 = ?
useful conversion: 1 meter = 100 centimeters
first, we convert the given with units of centimeters into meters:
480 centimeters = ? meters
to do this, we just divide 480 by 100 or:
480/100 = 4.80 meters
98/100 = 0.98 meters
then we add these two to get the total length that he cut and used:
4.80 + 0.98 = ?
now solve for this one~
after you have added them, you subtract this to the total length, which is 25 meters (given in the problem):
25 - (4.80 + 0.98) = ?

hope this helps~ :)
4.80+0.98=5.78-25=-19.22
