(10 + 10)/10 = 20/10 = 2. So you now have used 3 of the tens, just do the same again and you've used six tens and have another 2. Then you can have 2+2 = 4, or 2*2 = 4.
Here's another way: (10 + 10 + 10)/10 =3. Then add (10/10) which is 1, to get 4.
4 10s equal 10+10+10+10 6 10s equal 10+10+10+10+10+10
One possible way: Make a 10 using five 4s as follows: 4 + 4 + (4 + 4)/4 = 10 Make another two 10s using five 4s in each. Multiply these three 10s.
Forty points is equal to 40/100s or 4/10s of a carat -- almost half a carat.
six
There are no fractions between 8/10s and 4/5s because those fractions are equal. In decimal form they equal .8
It is: 36/4 = 9

4 + 2 = 6 Six is correct.
