Bonjour,
A = 3/21 = ( 3 ÷ 3 ) / ( 21 ÷ 3 ) = 1/7
B = 121/11 = ( 121 ÷ 11 ) / ( 11 ÷ 11 ) = 11/1 = 11
C = 100/1000 = ( 100 ÷ 100 ) / ( 1000 ÷ 100 ) = 1/10
D = 74/64 = ( 74 ÷ 2 ) / ( 64 ÷ 2 ) = 37/32
E = 3⁵/3⁷ = ( 3 × 3 × 3 × 3 × 3 ) / ( 3 × 3 × 3 × 3 × 3 × 3 × 3 ) = 1/9
F = 35/13 n'est pas simplifiable car 35 et 13 n'ont aucun diviseur commun.
G = 234x / x = 234
H = 3x² / x³ ( je te laisse faire celui là .. )
I = 44ab/6b = ( 44ab ÷ 2 ) / ( 6b ÷ 2 ) = 22ab/3b = ( 22 ab ÷ b ) / ( 3b ÷ b ) = 22a/3
J = 14/7x = ( 14 ÷ 7 ) / ( 7x ÷ 7 ) = 2/x
K = 36z/4 + 2 = 36z/6 = ( 36z ÷ 6 ) / ( 6 ÷ 6 ) = 6z/1 = 6z
L = 99-9/23 + 7 = 90/30 = ( 90 ÷ 30 ) / ( 30 ÷ 30 ) = 3/1 = 3
Je te laisse finir
