19. connor cuts a board with a length of 78.5 centimeters into four equal pieces. which is the best estimate for the length of each piece? a 2 cm b 5 cm c 20 cm d 25 cm

Answer

Explanation:

Step1: Identify the operation

To find the length of each piece, we divide the total length by the number of pieces. So we need to calculate (78.5\div4).

Step2: Estimate the division

We can round (78.5) to a number that is easily divisible by (4). (78.5) is close to (80). Then (80\div4 = 20). So the best estimate for (78.5\div4) is around (20) cm.

Answer:

C. 20 cm
