A heterozygous white sheep means it has one of each trait (Ww).
A sheep with black wool is assumed to be homozygous because black wool is recessive (ww).
You can create a punnet square for Ww x ww.
W w
—————————-
w | Ww | ww |
|————+————-|
w | Ww | ww |

When dividing fractions you keep the first fraction, change the division sign to multiplication, and flip the second fraction. (Keep Change Flip) For mixed numbers, make it a fraction by multiplying the whole number times the denominator, adding that to the numerator, and put that sum over the same denominator. Then do Keep Change Flip
A meter is 100 cm. A ball of string has 10m of string, and you multiply 10m by 100cm, you get 1,000cm. Then you multiply 40cm by 2, and you get 80cm, or two lengths of string. Then you multiply 35, which is half of 70, by 80, and that is 2,800 cm.2,800÷40cm=70And 100cm=1m.The teacher will therefore need 28 balls of string.
