Cost means 32 degrees, 44 minutes and 24 seconds; cost, minutes and seconds means 54.12 degrees

24 seconds = 0.4 minutes,
44.4 points = 0.74 degrees
So 32 degrees 44 minutes 24 seconds = 32.74 degrees
12 degrees
=54 degrees + 0.12 * 60 points
=54 degrees 7.2 points

Calculation method: take the integer unit, multiply the decimal part by 60, then take the integer part as the next level unit, and multiply the decimal part by 60

How many degrees is 216 degrees 42 minutes

216.7 degrees
42 divided by 60 equals 0.7
0.7+216=216.7°

Using the same brick to pave 42 square meters of ground, we started to pave 18 square meters, and used 216 pieces. According to this calculation, how many more pieces will be needed to pave the fast ground
Equation do

It takes a total of X pieces to complete the bottom
216:18=x:42
18x=42×216
x=504
504-216 = 288 (pieces)
A: 288 more pieces are needed to finish the paving
You can ask me if you don't understand my answer!

With the same square brick paving area of 42 square meters, we started to pave 18 square meters 216 bricks. According to this calculation, if we finish paving this floor
How many more bricks do you need?

(216 ÷ 18) × 42 = 12 × 42 = 504 (pieces), 504-216 = 288 (pieces) a: 288 more bricks are needed after paving this floor
