e) 248' : 8 = 31⁰
ꨄ︎ 28
☀︎︎ 1⁰ = 60'
a) 16⁰ 48' + 65⁰ 50' = 81⁰ 98'
= 82⁰ 38'
b) 71⁰ - 24⁰ 34' = 70⁰ 60' -24⁰34'
= 46⁰ 26'
c) 15⁰ 25'+38⁰41'- 16⁰ 52' =
53⁰ 66' - 16⁰ 52' = 37⁰ 14'
d) 12⁰ 36' × 8 = 96⁰ 288'
= 100⁰ 48'
e) 14⁰ 27' × 7 = 98⁰ 189'
= 99⁰ 129'
= 100⁰ 69'
= 101⁰ 9'
f) 147⁰ : 2 = 146⁰ 60' : 2
