Answer:

2.93cm

Step-by-step explanation:

I have to admit, this stumped me but I got o work and here's what I have for you. Hope this helps. TIP: remember it is the minute hand not any other hand.

For this one you will have to find the circumference of the clock because as the min hand goes round and round, it will act as a radius and it will go in a circular motion.

Formula will be π2r= 3.l4 * 2 * 1.4cm=8.792cm per every one revolution of the minute hand. Remembering that for the minute hand to revolve round the clock it has to cover 1 hr = 60min. For you to get the total circumference,

you'll have to take 8.792cm but since it is per every one revolution of the minute hand, multiply it by 40/60min. The answer will be 2.93066cm before rounding off. After rounding off you will have 2.93cm. Quite lengthy but I assure you after practicing you'll have at your fingertips.

A unit fraction is a fraction whose numerator is 1.

$\frac{12}{84}=\frac{12 \div 12}{84 \div 12}=\frac{1}{7} \\ \\
\frac{13}{143}=\frac{13 \div 13}{143 \div 13}=\frac{1}{11} \\ \\
\frac{23}{138}=\frac{23 \div 23}{138 \div 23}=\frac{1}{6}$
