Answer:
4 (5/12). four and five-twelfths
Step-by-step explanation:
1/2 is the same as 2/4, so: 1 1/2 = 1 2/4
1 2/4 + 2 1/4 = 3 3/4
3/4 and 2/3 have a LCM or least common multiple of 12
4 x 3 = 12 and 3 x 4 =12; but whatever you do to the bottom you have to do to the top (3/4) turns into (9/12) and (2/3) turns into (8/12)
9/12 + 8/12 = 17/12 or 1 5/12 as a mixed number
3 + 1 5/12 = 4 5/12

Answer:
50
Step-by-step explanation:
and
can be expressed in complex form, with
= i
=
=
×
= 8i
=
=
×
= 4i
the factors can then be expressed as
(6 + 8i)(3 - 4i) ← expand using FOIL
= 18 - 24i + 24i - 32i² [ i² = (
)² = - 1 ]
= 18 - 24i + 24i + 32 ← collect like terms
= 18 + 32 + 0
= 50
