Ai lam nhanh nhat , dung nhat minh tick cho . Huaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa do .
Tìm y phân số:
a. y : 2/3 = 4/9 x 3
b. 5/6 + y/12 = 7/6
giúp mình với, trả lời mình tick cho
1; y - 2/4 =1/2
2/9 +y = 1
y/4 =28
3: manh vuon hinh chu nhat co chieu rong bang 2/5 chieu dai va chieu dai hon chieu rong 24m tinh dien tich
4; tinh tong:
1,2,3,4...,9
viet cach lam ra nhe
tinh gia tri cua bieu thuc
7/5-6/5:3
tim y
y*6/7=3/4+2
AI TRA LOI DUNG THI MINH TIK CHO
Tìm y
a } 4 / 5 x 3 /y x 2 / 11 = 24 / 165
b } 4 / 3 : y / 5 = 5 / 13 x 4 / 9
Giúp mình với nhé!
Dùng đúng hay sai cũng được .Ai giải cho mình trước thì mình sẽ tích cho 3cái nhe !hello
a) \(y\) : 4/5 = 11/8
b) 11/3 - \(y\) = 1/9
c) 1/7 x \(x\) = 8/5
ai giải nhanh và đầy đủ tui sẽ tick là đúng (chọn 3 người giải nhanh và đầy đủ thui nhe)
1 Tìm x, y để số 42x7y chia hết cho cả 2; 5 và 9.
2 Tìm các chữ số a, b để a97b chia hết cho 5 và 9.
Ai giai duoc ca 2 bai minh tich nhe!
Tim y
y x 1/2 + 3/2 x y = 4/5
